Alonzo Mourning on Thursday went through his first full-contact practice with the New Jersey Nets since undergoing a kidney transplant surgery 10 months ago.

Mourning, 34, is attempting to be the second pro athlete to return from a kidney transplant. The first was former San Antonio Spurs swingman Sean Elliott, who played 71 games over two seasons after undergoing a transplant in 1999.

Until Thursday, Mourning had mixed occasional contact drills with strength-training, shooting and weightlifting.

"It is progress," Mourning said. "Every time I think about where I was and where I am today, I don't see too many transplant patients doing what I am doing now in less than a year whether it be kidney, heart, liver, any kind of transplant."

Mourning, who received the kidney from his cousin and underwent the surgery on Dec. 19, said he was winded after the practice. He wore a temporary kidney protective pad that he broke in himself.
